Answer:
the missing angle is 148°
Step-by-step explanation:
the sum of all exterior angles of a triangle are 360°
so, 360-138-74 = 148°
Answer:
Step-by-step explanation:
There's only 1 '6' on an ordinary die with 6 sides, so the probability of rolling a 6 is 1/6.
That of NOT rolling a 6 is the complementary probability: 1 - 1/6 = 5/6.
Answer:
8 out of 84: 90% decrease
200 out of 238: 16% decrease
Step-by-step explanation:
To find a percent decrease, you first subtract the end number by the initial number. This gives you the change.
ex. 84-8=76
Now you divide the change by the initial number. You'll get a decimal.
ex. 76/84=0.904...
Multiply the decimal times 100, or move the decimal to the right twice.
ex. 0.904... -> 90.4...
Now round to the nearest ones place
ex. 90.4 -> 90%

Answer:
y = -x +9
Step-by-step explanation:
The equation will be written in slope-intercept form, y=mx+b
Looking at the graph, we can already see that the y-intercept is +9 since that is the point on the y-axis from where the line comes from.
Now, you have to find the slope. Normally, you would pick two points and subtract the y value of the second point and the y value of the first point and put the sum over the difference of the x value of the second point and the first point, y2 - y1/ x2 - x1.
You could have done this or looked at the graph to see that the line has a constant downward slope of -1, go down one and to the right one from (0,9) t ok end up at (1,8).
All that's left to do now is to plug the values of the slope and y-intercept in to give us the equation y = -x +9.
